in .bashrc keeps 2000 lines in your history file, and bash commands that are duplicates of the last bash command are not added

typing history displays the bash commands history

alias h='history' lets you type h instead of history

if you add SHELL=/bin/bash to /etc/profile, rxvt and aterm will run bash automatically

you can symlink /usr/bin/bash to /bin/sh and bash will run as your default shell (whenever /bin/sh is run) ... you need to symlink busybox to /bin/sh before you shut Puppy down ... be careful, you can easily stop Puppy from booting if you setup the symlink wrong in rc.local
